Resumen
Uno de los pasos fundamentales para la realización de un correcto
tratamiento de Endodoncia es determinar la longitud de trabajo. El
ápice radicular junto con la constricción apical forma el área final y
más estrecha del conducto, la cual va al ligamento periodontal que
casi nunca se encuentra en el vértice del diente. La importancia de la
existencia de esta zona nos delimita el espacio para instrumentar y
obturar el conducto. La constricción apical no es posible verla
radiográficamente, donde el objetivo es llegar a 1 mm menos del
ápice radiográfico. Por lo mencionado, en la actualidad se ha hecho
indispensable la utilización de los localizadores apicales en la
Endodoncia actual, los cuales en diversos estudios demuestran
efectividad. El objetivo de este estudio es la aplicación del
conocimiento técnico y científico para obtener la longitud de trabajo
ideal con el localizador de ápice Propex Pixi, para realizar un
tratamiento de conducto de forma correcta. Este trabajo tuvo la
participación de 10 pacientes en el periodo 2014 - 2015, se les realizó
la apertura inicial del diente, seguido de la conductometría con el
localizador apical observando en la pantalla del aparato la medición
y seguido de una radiografía de comprobación. También se logró
comparar el localizador de ápice, con los estudios radiográficos de
Ingle y Bregman. Todo lo antes mencionado fue parte de las
investigaciones que se realizaron para llevar a cabo una conclusión.
Se concluye que el localizador de ápice Propex Pixi logra obtener un
alto grado de exactitud en la obtención de la longitud de trabajo en
comparación con los métodos de Ingle y Bregman, pero el
localizador obtiene una exactitud muy pobre en la segunda cita,
siendo superado por los métodos de Ingle y Bregman.
The most important step for an endodontic treatment is a good working length determination. The root apex with apical constriction forms the end and narrower duct area on the teeth, which its output goes to the periodontal ligament that almost never found in the apex of the tooth. The importance of the existence of this area is that we will define the space to implement and seal the duct. The disadvantage and risk as a dentist can lead to perform a root canal, is that the apical constriction is not possible to see radiographically, where the primary objective is to reach 1 mm less than radiographic apex. As mentioned above, today has become indispensable use of apex locators in the current endodontics, which in several studies demonstrate effectiveness. The aim of this study dealt with the application of scientific and technical knowledge to get the working length and be able to perform a root canal properly with the Propex Pixi apex locator. This work had the participation of 10 patients in the period 2014-2015, the steps that I need is the initial opening of the tooth followed by the apex locator, watching on the screen measuring device and followed by an x-ray test. It was also possible to compare the apex locator with radiographic Ingle and Bregman studies. All of above was part of the research conducted to carry out a conclusion. I conclude that the Propex Pixi apex locator is possible to obtain a high degree of accuracy in obtaining the working length compared with the Ingle and Bregman methods, but the locator gets a poor accuracy on the second date, being surpassed by Ingle and Bregman methods
